FCC Notice (for U.S. Customers):
This device complies with part 15 of the FCC Rules:
Operation is subject to the following conditions:
1. This device many not cause harmful interference, and
2. This device must accept any interference received, Including interference that may cause
undesired operation
Warning:
Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
Operation of this device is restricted to law enforcement, fire and rescue officials,
scientific research institutes, commercial mining companies, and construction
companies. Operation by any other party is a violation of 47 U.S.C. § 301 and could
subject the operator to serious legal penalties.
Coordination Requirements.
(a) UWB imaging systems require coordination through the FCC before the equipment may
be used. The operator shall comply with any constraints on equipment usage resulting from this
coordination.
(b) The users of UWB imaging devices shall supply detailed operational areas to the FCC
Office of Engineering and Technology who shall coordinate this information with the Federal
Government through the National Telecommunications and Information Administration. The
information provided by the UWB operator shall include the name, address and other pertinent
contact information of the user, the desired geographical area of operation, and the FCC ID number
and other nomenclature of the UWB device. This material shall be submitted to the following
address:
Frequency Coordination Branch., OET
Federal Communications Commission
445 12th Street, SW
Washington, D.C. 20554
ATTN: UWB Coordination
(d) Users of authorized, coordinated UWB systems may transfer them to other qualified
users and to different locations upon coordination of change of ownership or location to the FCC and
coordination with existing authorized operations.
(e) The NTIA/FCC coordination report shall include any needed constraints that apply to
day-to-day operations. Such constraints could specify prohibited areas of operations or areas
located near authorized radio stations for which additional coordination is required before operation
of the UWB equipment. If additional local coordination is required, a local coordination contact will be
provided.
(f) The coordination of routine UWB operations shall not take longer than 15 business days
from the receipt of the coordination request by NTIA. Special temporary operations may be handled
with an expedited turn-around time when circumstances warrant. The operation of UWB systems in
emergency situations involving the safety of life or property may occur without coordination provided
a notification procedure, similar to that contained in CFR47 Section 2.405(a)-(e), is followed by the
UWB equipment user.
NOTICE: Use of this device as a wall imaging system is prohibited by FCC regulations.

System Settings and User Notes
Model 5100 Antenna
The Model 5100 antenna has greatly improved performance over previous high frequency
antennas. Not only is the frequency higher, but the antenna has the ability to see objects at very
close distances.
System Setup - Standard Settings
Note: These setup instructions will allow you to properly use the Model 5100 antenna.
Setup Mode: Manual
System Run Mode: Distance/Survey Wheel (recommended) or Continuous
Range: 6-20 ns
Number of Gain Points: 3-5
Vertical Low Pass Filter: 3000 MHz
Vertical High Pass Filter: 250 MHz
Vertical High Pass (IIR): 10 MHz
Samples per Scan: 512
Bits per Sample: 16
Scans per Second: Set to the maximum scan rate allowed by the SIR System used
Signal Position
Place the antenna on the
concrete floor and use the
Automatic Signal Position
selection. You may need to
try this 2 to 3 times to get
the system to lock on to the
surface pulse. If after 3
tries, the surface pulse is
not in the signal window,
point the antenna into the
air and again try the
Automatic Position.
To test that you have the
correct position, raise the
antenna off the ground and
you will observe on your system that the antenna transmit pulse will separate from the reflection
from the ground. The higher that you raise the antenna, the further apart will be the two pulses.

Gain Check
The surface pulse should be about 2/3 the width of the screen. If it is
greater, reduce the Gains manually. If the signal appears too small, you
can manually increase the Gains, but the first gain point should never
exceed 10dB.
Minicart
Your Model 5100 is designed to fit into the Model 615 minicart. Using the
antenna with the minicart allows you to take advantage of distance-based
data collection which is possible with a survey wheel. A survey wheel (rear-axle of the cart)
tracks the distance traveled and allows consistent scan spacing. The minicart is available as a
separate purchase and is also compatible with the Model 5101 antenna. Please contact your GSSI
sales representative for details.
Note: The Model 5100 is not intended for use as a wall or ceiling imaging device.

Data Collection
Collecting Data Using The Survey Wheel With The Standard Settings
System Run Mode: Survey Wheel
Number of Scans per Meter: 80 (24 scans per foot) or higher. GSSI StructureScan
concrete imaging systems collect 60 scans/foot or higher.
Remote Operation
This may differ depending on your control unit. See your control unit’s user manual for details.
•
Pressing the thumb marker switch on the 615 cart for less than one second will place a
marker in the data.
•
To put the system into Standby mode during data acquisition, press the button for more
than two seconds, but less than six seconds, then release the button.
•
Pressing the button for longer than 6 seconds will close any open files and turn off the
transmitter. To resume, the data acquisition sequence must be repeated.
Special Settings Used For Collecting Data On Bridge Decks
Setup Mode: Manual
System Run Mode: Survey Wheel
Range: 6 ns (unpaved), 10 ns (paved)
Number of Gain Points: 1
Vertical Low Pass Filter: 3000 MHz
Vertical High Pass Filter: 250 MHz
No Horizontal Filters
Samples per Scan: 512
Bits per Sample: 16
